Question 9
FIGUUR 9.1 toon 'n bandaandrywingsstelsel met 'n 230 mm-dryfkatrol. Die bandspoed in hierdie stelsel is 36 m.s⁻¹. Die trekkrag in die stelsel is 140 N en die verhoud... show full transcript
Step 1
Answer
Om die rotasiefrekwensie van die dryfkatrol te bereken, gebruik ons die formule:
V = rac{n imes ext{D}}{60}
Hierbinne is:
Eerstens bereken ons die omtrek van die dryfkatrol:
Hierna kan ons die rotasiefrekwensie bereken:
n = rac{V imes 60}{ ext{π} imes D} = rac{36 imes 60}{ ext{π} imes 0.23} \\ = 2989.35 ext{ r/min}
Step 2
Step 3
Answer
Vir die inset-as se rotasiefrekwensie, gebruik ons die verhouding tussen die tande:
N_{ ext{inset}} = N_{ ext{uitset}} imes rac{T_b imes T_{ ext{C}} imes N_{ ext{uitset}}}{T_a imes T_d}
Hier is gegewe:
Die rotasiefrekwensie van die uitset-as kan hierna berekend word:
Volgende kan die tussenas se rotasiefrekwensie bereken word, wat gegee word as:
Hierna kan die rotasiefrekwensie saam met die gegewe waardes bereken word.
Step 4
Answer
Die berekening van lugslakke kan gebaseer wees op die tande en die rotasies waarvoor die dryf meganisme in plek is. Dit behels die verhouding en hoe die lugslakke met die elektriese motor geaktiveer moet word of nie. Dit moet ook oorweeg word hoeveel tande optel op die dryfwenke tussen die komponent.
